readily for disengaging them when it is de-' sired to clean the razor or replace the blade.

Threaded connections have been used here tofore with satisfaction in respect to clamping eficiency and reliability. I contemplate a connection which will possess these same advantages, but in addition thereto will be capable of more rapid engagement and disengagement, with the result that the shaver may save time both in the operation of assembling his razor and of disassembling or taking it down.

In the type of razor wherein the holder comprises a cap, guard, and handle, my invention may be embodied byproviding a hook connection between the handle of the cap, such that the guard is interposedbetween the two and forced into blade-shaping position with respect to the cap by the movement of positioning the handle. This con- 0 struction permits the use of eficient cam surfaces for efiecting the clamping engagement. Moreover the same pressure which efiects the blade-shaping operation is efiective to maintain the handle in its operative position.

Similarly the single movement of the handle into disengaging position releases the clamp and guard so that they may be immediately separated to disengage the blade.

I prefer to utilize a cross in in the con- 40 struction of the hook connectlon and to provide the blade with an aperture through which the cross pin may be passed in assembling the razor. An advantae incident to the construction is that the lade may be located between the'blade-shaping members by a tongue having an elongated contour similar. to the cross pin and thus is obviated the necessity for separate blade locating studs. So far as I am aware itis broadly new to utilize an elongated opening in the blade for the purpose of accommodating an element of the connecting means and also for the purpose of locating the blade in the assembled razor.

These and other features of the invention will be best understood and appreciated from the following description of a preferred embodiment thereof, selected for purposes of illustration and shown in the accompanying drawings, in which- Fig. 1 is a. view in perspective of the parts 'of the razor separated from each other but arrangedin order for assembling.

Fig. 2 is a view in side elevation showing the razor handle in position for disengagement.

Fig. 3 is a View in side elevation showing the assembled razor, and

Fig. dis a view in perspectiveof'the assembled razor with the handle in telescoped condition.

In the razor herein shown the blade-shaping members comprise a cap 10 and a guard 24. The cap 10 is provided with a convex outer face and with an inner concave bladeshaping face. A post or studl2 of rectangular cross section extends upwardly from the blade-shaping face of the cap. At its upper end it is rounded and'provided with a crosspin 16 which projects symmetrically from opposite faces of the stud 12. An elongated rib 14 projects through the stud 12 upon the blade-shaping face of the cap 10, this corresponding substantially in contour with the cross-pin 16, being of substantially equal len h and width and rounded on its upper sur ace to facilitate positioning of the blade.

The cap 24 is provided with a lower bladeshaping face and with the guard teeth 25 along its longitudinal edges. It is provided with a, central-aperture shaped to receive the stud 12 and cross in 16 of the cap, that -is to say it has a wi e central rectangular the cross section A central portion 20 of rectangular outline and an elongated slot 22 corresponding in length 7 and width to the cross pin 16 and rib 14.

The handle comprises a solidportion 30 and a hollow telescopic portion-38. As herein shown the handle is square in cross section but this is a matter of design and of secondary im ortance onlyp The solid portion is pro- .vi ed at'its upper end with a tapering enlargement 36 w ich cooperates with a correspondingly contracting lower end of the hollow portions 38 preventin separation oi the two and holding them rictionally in expanded condition when so positioned by the user.

The lower end of the portion 30 oi the handle is slotted longitudinally forming spaced arms or branches 34 arranged to embrace the opposite faces of the stud 12 and cutaway in'one face so as to form books with openings corresponding substantially in width to the diameter of the crossnin 16. Each arm 34- of the handle is provided with a transverse rib -32 inclined slightly downwardly and rearwardly with respect to the hook openings as shown in Fig. The bottom surfaceol each rib 32 merges into the bottom surface oi its associated arm 34 and, being sli htly rounded eccentrically with respect to the center the heel: opening, acts as a cam surface to ilorce the guard downwardly when the handle is swung into an upright position. lhe end or bottom face of the handle is square and substantially perpendlcular to the axis of the handle and the ront face of the handle'below the hook open= ing is also flat but is di osed at a slight inclination to the axis oi t e handle.

In assembling the illustrated razor the 1 blade 18 is first placed upon the cap 10, being located thereon by the action of the rectangular stud 12 and the rib 1a in the aperture in the blade. It will be seen that the aperture in the blade not only permits the passage of the cross pin 16 but cooperates with the rib 14 beneath it in determining the shaving position of the blade. The guard member 24 is then positioned above the blade, be-

ing similarl located by the stud. The handle 1s then hooked upon the cross pin 16 in an lIlQlll'lBd position as shown in Fig. 2 with its inclined front face in contact with the guard. When it is desired to clamp parts of the razor in condition for shaving the handle is swung in a clock-wise direction from the os ition shown in Fig. 2 to that shown in n ig. 3. In this movement the cam surfaces formed'by the sides of the hook act 'to depress the guard 24 against the yielding res1stance of the blade 18, until the corner of the handle has passed from beneath the crosspin 16 and the handle reached its upright position.- In effect this movement of the handle forces the guard and cap together by relatively moving the guard and cross pin to such position that the blade is fully shaped between the cap and guard. The handle is maintained 'with considerable rigidity in its upright position with its flat end surface in engagement with the fiat upper face of the guard 24 and with the cross pin 16 resting upon the inclined upper faces of the ribs 32.

The razor is now ready for. use and may be employed with the handle in elongated position as shown in Fig. 3 or with it in telescopic position as shown in Fig. l in accordance with the preference of the user.

When it is desired to separate parts of the razor the handle is forcibly returned to its inclined position, there being suficient resiliency in the parts to permit the slight contracting movement of the cap and guard necgssary to permit this movement of the hanle. by moving it to carry the cross pin 16 out of the hook, whereupon the guard may be lifted and the blade 18 exposed.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is l. A safety razor havii blade shaping members, a stud projecting from one member through the other and having a cross pin, and a quick-detachable handle having square ended s acedhoolrs shaped to embrace the stud an engine both the cross pin and the face of the 'ad acent blade-shaping member a and movable with a camming action to clamp said blade shaping members together in reaching a position of stability.

2. A safety razor having blade shaping members, one having a stud with across in and rib beneath the cross pin, and the ot or having an aperture for this stud and a slot for the passage of the cross pin, and an interposed blade having a locating slot-shaped to t the rib of the blade-shaping member first The handle is now free to be detachedmentioned and to permit the blade to be passed over the cross pin of the stud.

3. A safety razor having blade-shaping members, one havin a stud with a cross pin and a rib on its face eneath the cross in and parallel thereto, the other member being apertured for the stud and pin, an interposed blade having a locating slot shaped to permit the blade to be passed over the cross pin and to be located by the rib, and a handle arranged to be connected to the cross pin and acting to secure the blade-shaping members together.

4. In a safety razor, a .cap having a concave blade-shaping face, a centrall disposed post projecting from said cap an havm a longitudinally disposed rib at its foot, an a cross pin extending in parallel relation to the rib and at least as longas the rib.
